SANITARY HOLDER For. snaps-anions.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed. January 21., 1918. Serial No. 743,832.

T 0 all whom it may concern:

Be it known that we, GARRETT L. Gninn and FRANK L. Game, citizens of theUnited States, and residents of Milford, in the county of Sussex andState of Delaware, have made certain new and useful improvements inSanitary Holders for Shade- Guides, of which the following is aspecification.

()ur invention relates to improvements in means for holding shadeguides, and it consists in the combinations, constructions andarrangements herein described and claimed.

An object of our invention is to provide a device for'holding samples ofcement that are to be used as shade guides so that the latter may be ina moistened state and instantly ready for use in determining the bottleor other shade of cement to be used in filling a tooth:

A further object of our invention is to provide a holder for the'shadeguides which. will keep the latter free from dust or germs that mightcome in contact with them if kept in a drawer or upon a table.

A further object of our invention is to provide a holder which will fitreadily into the palm of the hand but which will permit the readyselection of the difierent samples.

Other objects and advantages will appear in the following specification,and the novel features of the device will be particularly pointed out inthe appended claims.

- Our invention is illustrated in the accompanying drawings forming partof this application in which- Figure 1 is a vertical section through thedevice, Fig. 2 fs an enlarged perspective view of the suspending ringand a portion of the strips, and Fig. 3 is a sectional view of amodified form of the device.

The process of matching cement samples with teeth in which the apparatuswhich formsthe subject ofv he present invention is used is set forth ina copending application, Serial No. 743,333, filed Jan. 21, 1913.

In carrying out our invention we provide a similar receptacle 1 of theshape shown in Fig. 1. This bottle is provided with a stopper 2 of thesame material, and having a handle or knob 3. The underside of thestopper is provided with a bore 4 arranged to receive the stem 5 of aring 6.

In the drawings we have shown the stem 5 as consisting of the adjacentends of the ring 6 although it may be a single integral stem withoutdeparting from the spirit of the invention. This stemjs held in the borel by means of cement 7.

Suspended from the ring 6 are a series of strips 8 which are slidable onthe ring and also have a pivotal movement with respect thereto. Thesestrips are preferably of a thin resilient waterproof material, such ascelluloid, or the like, and bear at their lower end the shade guides 9.The latter are really pieces of cement of various tints or shades, eachformed in the shape of a tooth. As will be seen from the drawing, thelower ends of the strips 8 with the cement samples are submerged beneathwater.

In filling a tooth with cement it is often difiicult to attain the rightcolor. The cement is put up in the form of powder and is mixed withphosphoric acid into a paste, and one is very liable to get the cementfill ing either darker or lighter than the tooth itself. With ourprocess, however, this liability The cement shades or samples arealready made up and are kept submerged under water in the bottle 1. Whenit is necessary to determine the shade of cement to be used the stopper3 is removed and held in the palm of the hand, while the strips 8 areseparated with the fingers, and the cement samples or shade guides intheir moist condition may be placed along side of the tooth to betreated. Unless the cement is moistened it will not be of the shade thatit has when placed in the cavity of a tooth, for when the cement is dryit will appear generally of a lighter shade. The shade guides arenumbered to correspond with the powders from which they are made, sothat the proper shades can be readily ascertained. As soon as theselection is made, the stopper is returned to its place, the shadeguides again being submerged in the water where they are tamination andready for instant use.

It will be seen that the placing of the shade guides under water serve adouble purpose. It keeps them in a moistened condition so that they donot have to be moistened when they are removed from the bottle, besideskeeping them in a perfectly sanitary state. The stopper 2 serves, as

of error is reduced to a minimum.

kept free from con-- shade guides with the fingers and also as a meansof suspension for the shade guides when the latter are submerged inWater.

In Fig. 3 we have shown a modified form of the device in which thebottle 1 is provided with a cap 10. The neck of the bottle is providedon the interior with inwardly projecting lugs 1*. The ring 6 whichsupports the strips 8 bearing the shade guides 9 is adapted to rest onthe lugs 1 and a handle 11 is provided for lifting the shade guidesoutof the bottle when they may be used as already described.

We claim:

1. In a sanitary holder for shade guides,

a receptacle for containing Water, a series of shade guides, and meansfor suspending said shade guides in the water in said receptacle, saidsuspending means constituting a common handle for said shade guides.

2. In a sanitary receptacle for containing Water, a series of shadeguides, means for pivotally securing said shade guides together, meansfor suspending said pivotal means to permit the immersion of the shadeguides in the water in the receptacle, and a closure for said receptacleadapted to surmount said shade guides when the latter are immersed inWater.

'8. In a sanitary shade guide holder, a covered receptacle forcontaining water, a series of shade guides pivotally secured together,means for suspending said shade guides in the water, in said coveredreceptacle, and a common shade guide holder, a

handle for the series' of shade guides, said common handle also servingas a closure for the receptacle.

4. A- sanitary shade guide holder com prising a receptacle forcontaining Water, a plurality of strips pivotally secured together andbearing cement samples at their lower ends, and a stopper for saidreceptacle, the pivotal support of said strips being securedto saidstopper.

5. A sanitary shade guide holder comprising a receptacle for containingwater, a plurality of strips bearing cement samples at their lower ends,a ring for suspending the said strips, a stem secured to said ring, astopper for the mouth of said receptacle provided with a bore on itsunder side adapted to receive said stem, and means for retaining saidstem within the bore.

6. A sanitary shade guide holder comprising a receptacle for containingwater, a plurality of strips bearing cement samples at their lower ends,a ring for suspending the said strips, a stem secured to said ring, astopper for the mouth of said receptacle provided with a bore on itsunder side adapted to receive said stem, and means for retaining saidstem Within the bore, the cement samples being normally underneath thewater when the stopper is in the mouth of the receptacle.
